Mon Mar 15 08:48:48 2004  Jonathan Blandford  <jrb@gnome.org>

        * gtk/gtkfilechooserentry.c (match_selected_callback): implement
        correctly.
        (completion_match_func): Allow surpressing popdowns.
        (maybe_append_seperator_to_path): New function to add a separator
        item to a display_name.  Bad hack.
        (check_completion_callback): Implement select-ahead as an idle.
        (add_completion_idle): new function to handle select-ahead
        (gtk_file_chooser_entry_do_insert_text): starf the select-ahead
        idle.
        (gtk_file_chooser_entry_focus): Override tab for completion.
        (gtk_file_chooser_entry_activate): commit select_ahead when
        activated.

        * gtk/gtkfilechooserdefault.c (location_popup_handler): grab the
        appropriate widget for the mode.
